Describe the bug

I have followed the Deploy to production :
https://www.ory.sh/docs/kratos/guides/deploy-kratos-example

But I get a 404 Not Found

Reproducing the bug

When running npm start from the /opt/uinode/ui/ folder and I accessing the http://0.0.0.0:3000 page, it works, at least the first page, where I get the "Welcome to Ory" page, but it leads to https://playground.projects.oryapis.com login.

But using the uinode.service file and the nginx configuration, I get an error 404.
